a type of policy in which the insured is covered for any incident that occurs (or occurred) while the policy is (or was) in force, regardless of when the incident is reported or when it becomes a claim. Occurrence insurance for medical liability coverage is rarely offered today because of the difficulty in projecting long-term claims costs under this type of policy.
A policy form that provides liability coverage only for injury or damage that occurs during the policy period, regardless of when the claim is actually made. (See Claims Made Coverage)
A policy providing coverage only for injury or loss that occurs during the policy period, regardless of when the claim is made. For example, a claim made after expiration of a policy would be covered if the injury or loss occurred during the time the policy was in force. (See Claims-Made Coverage for comparison.)
